“I think it’s terribly irresponsible [not to reach out], especially since I own Sharon’s licensing so that I can help protect the way she’s viewed through the public’s eyes,” Debra Tate told PEOPLEback in March.

“These people are taking horrific situations and making them even more graphic than they were without any concern for the living victims of these crimes and I think that’s horrible and crass.”

However, after expressing her concerns, Debra has since revealed that after the director approached her, she had a change of heart and now fully supports his vision.

“I’m pleased he reached out,” Debra told PEOPLEabout Tarantino. “I thought it showed a lot of class and sensitivity to move up the release date.”

“He has done nothing but respect me and be very forthcoming. I have very high hopes for this project,” she says.

Sharon Tate was eight-and-a-half months pregnant when she and four friends were brutally murdered in her Los Angeles home in 1969 by Susan Atkins, Patricia Krenwinkel, and Charles "Tex" Watson in a shocking crime orchestrated by cult leader Charles Manson.

At the time of the murders, she was married to director Roman Polanski, who was in Europe filming a movie during the time of the horrific killing spree.

Tarantino’s upcoming film based on the murders will showcase a star-studded cast, including Leonardo DiCaprio and Brad Pitt -- with Aussie Margot Robbie now confirmed to play the role of Tate.

Once Upon A Time In Hollywood is set to open worldwide on July 26, 2019.
